This is what I'm saying. It's not like China does not have young couples. They simply are not given an opportunity to develop, since the Fed. preferred to push up the 3 established pairs. Its probably a smart strategy to keep a pair for a decade, adding to its reputation, etc..
Just compare how many names we've seen from Russia say at Worlds since 1999 - when the first 4CC was held (B/S, P/T, T/M, O/S, M/T, K/S, B/L, well Borzenkova/Chuviliaev...I'm sure I forgot a couple), from Canada, or the US, - and still the same 3 from China.
Well, I'm actually not complaining, this is just an observation
